塑料污染是当今世界日益严重的环境问题之一。微塑料(MPS)在南海区中国海区的分布情况尚不完全清楚。基于2018年的航次数据，研究了南海西南部表层海水中MPS的空间分布、形态特征和化学组成。分析表明，海水中MPS的平均丰度为0.072±0.053个/m3，其中88.4%的MPS为2 mm。97.3%的MPS为纤维和碎片。聚对苯二甲酸乙二醇酯(PET)、聚氯乙烯(PVC)和玻璃纸是表面MPS的主要聚合物组分。南沙群岛表层MPS丰度(0.083±0.063个/m3)高于西沙群岛(0.032±0.01个/m3)。此外，南沙群岛发现的MPS聚合物类型较多，而西沙群岛发现的MPS薄膜较多。南沙群岛以PET和玻璃纸为主，西沙群岛以聚氯乙烯为主，未检测到玻璃纸。南海西南部表层MPS丰度低，聚合物种类繁多，岛屿之间以及陆上和近海之间存在明显差异，这是由于船舶交通和一些有人居住的岛屿产生的塑料废物造成的。
Plastic pollution is one of the growing environmental problems in the world currently. The situation of microplastics (MPs) in the South China Sea (SCS) is not yet fully understood. This study investigated the spatial distribution, morphological characterization, and chemical composition of MPs in surface seawater in the southwestern SCS, based on cruise data in 2018. Our analysis shows that the average abundance of surface MPs in seawater was 0.072 ± 0.053 particles/m 3 and 88.4% of MPs were 2 mm. 97.3% of MPs were fibers and fragments. Polyethylene terephthalate (PET), polyvinyl chloride (PVC), and cellophane were predominant polymer components of surface MPs. Higher MPs abundance (0.083 ± 0.063 particles/m 3 ) and bigger MPs sizes were found at surface water in Nansha Islands than in Xisha Islands (0.032 ± 0.01 particles/m 3 ). In addition, more polymer types of MPs were found in Nansha Islands, while more MPs films were found in Xisha Islands. PET and cellophane dominated in Nansha Islands, while PVC dominated in Xisha Islands with no cellophane detected. The surface MPs were low in abundance and diverse in polymers in the southwestern SCS with apparent differences between islands and between onshore and offshore, owing to plastics wastes from vessel traffics and some inhabited islands.
